SPECIFICATION forming part of Letters Patent No. 424,961, dated April 8, 1890.

Application filed February 14, 1889. Serial No. 299,896- (No specimens.)

To all whom it may concern:

Be it known that I, J osnrn CONCKLEN COOPER, of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Fuel Oompositions, for insuring the practically perfect combustion of the same, fully set forth in the following specification.

This invention relates generally to a composition adapted for use with carbonaceous fuel to insure the complete combustion thereof and prevent the waste of heat which now occurs by reason of the necessity of employing strong drafts in order to cause a sufficient volume of oxygen to be supplied to the fuel to aid its combustion.

The object, therefore, of the present invention is to provide for the more perfect combustion of fuels and the utilization of their heat values by adding substances thereto which shall insure the complete combustion of the gases (carbonic oxide and sulphur) with the admission of less atmospheric oxygen, and that will produce from a given amount of carbon fuel a greater volume of heat, or a given amount of heat, from the use of less fuel, while reducing the destructive effect of sulphur and other gases 011 the metal fir otther surfaces exposed to the action of the I am aware that it has been proposed to use various fire-kindling and fuel compoundssuch as a mixture of chloride of sodium, nitrate of potash, and sulphate of iron; of starch, nitrate of soda, and sulphate of aluminium; of Glaubers salts and wood ashes; of chloride and sulphate of soda and muriate of ammonia and water, and of chloride of sodium and sulphate of soda-but long experience with these compounds has failed to attach any great value to them 011 account of the (lifficultyin handling some of the ingredients, their bulky nature, cost, and liability to be rendered valueless by contact with an alkali, such as potash.

In Patent No. 27 9,47 9, granted to me June position composed of alumina as contained in alums, aluminous cake, or earths, chloride of sodium, and sulphate of soda, which, so far as my experience and observation goes, went far to overcome the difficulties encountered in using the old compounds; but it needed intelligent use, which, owing to the various c011- ditions under which it was used, it seldom got.

In the practice of my invention I use a compound which in practical use demonstrates the possibility of consuming carbonaceous fuels with a minimum of draft or atmospheric oxygen, preventing the Waste ordinarily incurred by heating large volumes of air not practically needed for combustion by the escape of large heat values in the form of carbonic gases not receiving the equivalent of oxygen necessary to form complete combustion without the aid of a compound adapted to insure the same, and the waste and destruction of furnace-linings and metal surfaces from the corroding or destroying action of the sulphur contained in the coal.

In the practice of my invention I take chloride of sodium or common salt. I also take aluminium, preferably sulphate of alumlna, as contained in the alums of commerce or aluminous cake or earths. I also take potasvariable proportions, according tothe character of the fuel or the method of using it; but for the ordinary combustion of coals or other carbonaceous fuels I prefer to take of common salt, by weight, five or six parts; of the alums or aluminous cakes or earths, two parts; of potash, if nearly pure in carbonate form, one part. I mix these together reduced to as fine a powder as possible, and if necessary prevented from caking or becoming hard by adding some coal-dust, ground coal, or other suitable material for that purpose.

I apply the compound dry by sprinkling it over the carbonaceous fuel or dissolve it in water for convenience of application, and use it in the proportion-of, say, twenty-four (24) ounces to forty-eight (48) ounces to each ton of carbonaceous fuel, making the application as complete and uniform as possible. The application of the compound maybe made at any time before using the fuel from five minutes to a year, if the fuel after the application is sheltered from the action of the elements.

lVhen the fuel is treated with this compound and ignited, a much greater flame is caused, showing its prompt action on the gases evolved in the combustion of the fuel; the heat. properties of the fuel are all availed of; the waste in the escape of unconsumed gases is greatly diminished, owing to the fact that much less draft is necessary to support combustion, and by its fluxing qualities the fuel is entirely consumed, leaving finer and lighter ashes free from clinker as the result. 13y aiding the first ignition of the fuel it enables heat to he produced more quickly, and as the quantity of atmospheric oxygen can be greatly reduced and the dampers and air-drafts closed or. considerably restricted, the heat is thereby utilized and its escape in the outlets greatly reduced. I also find that this compound rcduces the smoke of bituminous coals, and that all metallurgical operationssuch as smelting from the ores, n'ielting in furnaces or else Wherc-arc greatly facilitated by its action,

cleaner metal and of a better quality being the effect.

In all kilns orsimilar appliances the action ol." this ernnpound is effective by reason of the greater flame and heat produced and the freedom ot' the same from deleterious gascs,\vhich ordinarily are so destructive and damaging in their etfectas,"for instance, in potteries, brick and lime kilns, and similar works.

What I claim its- The herein-described compound for treat ing fuel, the same consisting of a mixture of chloride of sodium, sulphate of alumina, and carbonate of potash.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
